Sounds about right for this sort of manga. Rarely, if ever, do authors think and handle things right.
Resulting in cultural moral pollution as easily influenced (young) readers' values are developed off fiction.
Capital punishment and
justified homicide in defense of self and others is considered "evil" in some modern societies as a result.
Horribly warped/non-existent sense of self-preservation, legally prohibited, by elite who benefit. (And resulting horror stories.)
Then again, given what this series has shown with trope obsession with slavery...
...I wasn't expecting a hardcore-realistic well-built isekai universe or characters.
(I read
"Galactic Navy Officer Becomes an Adventurer" for that.)
